Patent Overview — US 9,986,227 B2
Title: Tracked automultiscopic 3D tabletop display
Patent number / application: US 9,986,227 B2; application US 15/626,532; pre-grant publication US 2017/0289530 A1.
Assignee: Disney Enterprises, Inc. (original assignee; assignment recorded 2017-06-19 from inventors Quinn Y. Smithwick and Christopher Stuart Gabriel).
Key dates (as listed): Priority date 2015-06-03; filing date 2017-06-19; publication date 2018-05-29; anticipated expiration 2035-06-03. Legal status listed as Active.
Purpose: The disclosure relates generally to glasses-free (autostereoscopic) three-dimensional displays, and more particularly to using a horizontally oriented display—a "3D tabletop display"—to present left- and right-eye images to one or more viewers without special glasses, headgear, or filters.
Plain-language scope: The background explains that conventional lenticular 3D televisions are mounted vertically, require a viewer to stay near a fixed position and height, have narrow fields of view (about 13 degrees), and repeat view zones, which can produce pseudoscopic or confused imagery. Interlaced image sets are typically generated assuming a fixed viewing distance, so rendering from tracked eye positions without adjusting camera separation (stereo baseline) and field of view causes depth distortion. The patent text frames a horizontal/tabletop 3D display as desirable where a displayed object appears supported on the surface, casts virtual shadows, and changes perspective appreciably between overhead and off-axis viewing. Classification data lists lenticular autostereoscopic image reproducers, viewer tracking, gaze detection, and 3D model manipulation (e.g., H04N13/305, H04N13/366, H04N13/383, G02B30/27, G06T19/006), and prior-art keywords include "display," "viewer," "content," "display element," and "lenticular."
What the excerpt does not establish: It does not set out the claims or their specific limitations, does not provide a full description or drawing analysis, and only partially includes the background. It also does not establish the list of cited prior art, examiner reasoning, or any litigation, ownership transfer, or validity facts—none of which were researched here.

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
